Our local LibDems are revolting... https://www.facebook.com/CllrShaffaqMohammed/
Unsurprising that they are wanting to be seen in opposition to the plans (and I say this as someone who'd love it, love it, if Option C was selected), it's easy to moan about any change, you can paint it to suggest that we are going to lose half of our Manchester services (just like that horribly disingenuous quotation from the Southport people was happy to give the impression that the incredibly important town full of Manchester University staff would see a 50% reduction in services to Manchester, rather than just having the same frequency but with everything serving the same central station).
To use completely made up numbers, there might be one hundred people in Sheffield who use the train to Manchester Airport each year and only ten people who use the train to commute to Manchester on a daily/regular basis - so a shameless politician (like Mohammed, with local elections around the corner) will appeal to the hundred (who'll see the direct service replaced by a change on the same island platform) rather than the ten (who'll have a more reliable service, and all trains using the same platform rather than some in the shed and some at 13/14).
However, for the railway, those ten people make significantly more journeys each year than a hundred people taking their annual holidays, and contribute a lot more in revenue (esp with Airport passengers booking on Advance tickets), so we need to balance the upset of a large(r) number of occasional passengers against the small(er) number of everyday passengers
Prior to the timetable change which meant Chester via Altrincham depart at around 20 to the hour, rather than just after quarter past, there were many times when I watched a South TransPennine service depart Manchester Piccadilly in the direction of Manchester Airport. The only occasions it had any noticeable number of passengers on board was when it was calling at stations between Piccadilly and the airport.
Even with the international students being referred to some only make one or two return journeys to the airport per year, as while they'd like to go home and visit family at Christmas and Easter, many stay in the UK due to high flight costs on dates around Christmas and Easter.
For example, Greenfield is 12 miles from Manchester, with a frequent direct bus route to Manchester and the metrolink close by. On the other hand Wigan and Golborne are 24 and 19 miles from Manchester respectively. Neither have a bus route to Manchester and the closest metrolink is about 12 miles away.
How reliable is the bus service in winter? I'm aware bus services between Stockport and Buxton and between Macclesfield and Buxton can get suspended when it snows but I've found North TransPennine to not really be any less reliable in bad weather than normally.
Option D is potentially anything anyone wishes to discuss in the speculative thread: https://www.railforums.co.uk/threads/we-need-to-talk-about-castlefield-again.204599/
I was actually wondering whether anyone knew what TfGM would be proposing as their official option D, given Mr Burnham is quoted as saying they will propose a 4th option which is none of the above but doesn't give any details on what that will contain. He can't know the 4th option is better overall for Greater Manchester if the 4th option isn't finalised and he does accept that there are limits to the number of services that can be accommodated in order to have a reliable service.
